Table 3 Main PERMANOVA test and pairwise comparisons (only significant variations are shown) of observed and recognized abundance data by month, regarding absent or small quantity of bio-fouling (F = 0) and different combinations of turbidity score (T). Numbers from 1 to 12 in the pairwise tests indicate months from January (1) to December (12).
